Lab Research Area:

The research goals of our laboratory are to characterize the cognitive and brain changes that occur during aging, as well as to develop behavioral and pharmacological strategies to attenuate mnemonic and neurobiological age-related alterations. Towards this goal, one of our primary interests is to determine the roles that sex, hormones, and brain chemistry play in brain function and cognition in young versus aged subjects. Our interests incorporate these goals with relevance to Alzheimer’s disease-related variables, and non-pharmacological approaches to protecting the brain and cognition against age- and neurodegenerative- related changes.

One of our main aims is to determine the effects that hormone therapies used in women have on the brain and its function across the lifespan. For example, we have been studying the effects of Premarin, estradiol, and progestins on cognition and neurobiology in different types of menopause. We are also evaluating hormones in contraceptives for effects on the brain and cognition across the lifespan. Findings demonstrate that estrogen and progesterone can have divergent effects on memory and neurobiology in aging females, and that effects of ovarian hormone loss and replacement are impacted by many parameters including menopause history, temporal specifics, and age.

Bimonte-Nelson Lab Members


Lab Director and Principal Investigator:  Heather Bimonte-Nelson, PhD

Dr. Bimonte-Nelson's undergraduate degree in Psychology was earned at Richard Stockton College, located near the beach in Pomona, NJ. To follow her interests in brain and behavior, she began her doctoral research under the mentorship of Dr. Victor Denenberg at the University of Connecticut where she focused upon sex differences in brain morphology and function, and how ovarian hormones affected the expression of sex differences in an activational and organizational fashion. The idea that gonadal hormones could have such a profound influence on the brain and behavior was intriguing to her and this area of work became her passion. After earning her PhD in 2000, she began a postdoctoral fellowship with Dr. Ann-Charlotte Granholm at the University of Colorado Health Sciences Center in Denver, and several months later, helped move the laboratory to the Medical University of South Carolina. In 2005, Dr. Bimonte-Nelson moved to ASU and founded the Bimonte-Nelson Memory and Aging Laboratory. When Dr. Bimonte-Nelson is not in the laboratory or teaching, she enjoys the beautiful Arizona atmosphere by spending time outdoors with husband, Matt, and their two teenage daughters. She also enjoys painting, music, concerts and writing short stories.

Postdoctoral Researcher

Stephanie Koebele, Postdoctoral Researcher. I am currently a postdoctoral fellow in Dr. Bimonte-Nelson’s Neuroscience of Memory and Aging Laboratory at ASU. I earned my PhD in this laboratory in Summer 2019 following the completion of my predoctoral National Research and Service Award (NRSA) funded by the National Institute on Aging. My research focuses on the cognitive and neurobiological effects of ovarian hormone loss during the menopause transition, including longitudinal cognitive changes following variations in surgical menopause. I am also an ASU undergraduate alumna with dual Bachelor’s degrees in Psychology and Spanish. Contact:   

Doctoral Students

Veronica Pena, Doctoral Student. I received my BA in Psychology with a concentration in Neuroscience from Carleton College in 2012, and graduated from the University of Texas at Dallas with a M.S. in Applied Cognition and Neuroscience in 2016. Currently, I am a graduate student in the Behavioral Neuroscience PhD program. My research focuses on how menopause and hormone therapy impact healthy aging as well as neurodegenerative disease, specifically Alzheimer's disease behavior and pathology.

Victoria Bernaud, Doctoral StudentI am currently a fourth-year doctoral student in Dr. Heather Bimonte-Nelson’s Behavioral Neuroscience of Memory and Aging Laboratory. I recently received my MA in Spring 2020 while enrolled in the Behavioral Neuroscience PhD program in the Department of Psychology. My research explores the effects that surgical and hormonal alterations to the female reproductive system have on neurobiological and cognitive functioning during aging. I am also an ASU undergraduate alumna, Class of 2017, with concurrent Bachelor of Science degrees in Chemistry and Psychology.

Ashley Ruhland, Doctoral Student. I am in the first year of my doctoral study under the direction of Dr. Bimonte-Nelson in the Neuroscience of Aging and Memory laboratory. I received my BA in Spring of 2018 from Winona State University with majors in Psychology and Spanish, and minor in Criminal Justice. There, I had the opportunity to work on faculty research and received a WSU Undergraduate Research Grant to perform an independent study evaluating learning and memory following progesterone administration. I look forward to the opportunity to further develop my research interests in the effects of ovarian hormones on cognition and neurobiology at ASU.

Taena Hanson, Doctoral Student. I am currently a first-year doctoral student in Heather Bimonte-Nelson's Neuroscience of Memory and Aging Laboratory at ASU. Though originally from Boulder, Colorado, I graduated in the spring of 2020 from Creighton University with a Bachelor of Science in Neuroscience. My research interests include how various hormones interact with different neurotransmitters in the brain and sex-based differences in drug activity. 

Lab Manager

Steven Northup-Smith: I graduated with a Bachelor’s degree from Grand Valley State University with a double-major in Psychology and Biopsychology and a minor in Biology. I joined the Bimonte-Nelson lab in the fall of 2016 as Lab Manager. I am broadly interested in cognition and behavior, and their neural correlates. Contact:

Undergraduate Research Assistants

Ana Arroyo: I was born and raised in Arizona but most of my family resides in our home town in southern Mexico. I am currently a senior at ASU as a first generation college student, I am majoring in Forensic Psychology and minoring in French. I am also in Barret, ASU's honors college. My interests lie in neuroscience and behavioral studies and I look forward to the opportunities ahead as I work with such an amazing team. 

Raena Johnson: I am originally from Tucson, Arizona and am currently a sophomore double majoring in Neuroscience and Psychology (BS). I am interested in studying the brain specifically regarding the factors that can affect behavior, including the impact of hormones and cognition. I intend on using the experience and knowledge gained in the lab as a stepping-stool towards a career in Neuropsychology. I joined in November 2018 and am thrilled to be a member of the Bimonte-Nelson lab participating alongside great mentors in the study of brain research!

Alyssa Manzo: Hello! I am currently a senior at ASU double majoring in psychology and neuroscience. I began my journey in Dr. Bimonte-Nelson’s lab the second semester of my sophomore year and have grown so much since then! Through my time in the lab I have added the neuroscience major, been on multiple projects with graduate and undergraduate students, and overall, increased my knowledge on memory and aging. I am thankful to work alongside multiple mentors and peers that motivate me to be the best I can be. My future goals are to attend graduate school and acquire the expertise necessary to become a clinical neuropsychologist. I am currently Co-Founder and President of the Swift Club at ASU. We volunteer at Title I schools, mentor youth, and encourage college education through fun after school activities. 

Zorana Opachich: I was born and raised in Phoenix Arizona and am currently studying Psychology and Neuroscience.  I started out in the lab in August of 2019 and have enjoyed being able to learn so much about hormones and their impact on physiology and behavior. I am very passionate about learning behavioral neuroscience and I plan to get a PhD once I graduate from ASU. 

Santiago Logan-Robledo: I was born in Mexico and raised in Chandler, AZ. I am going into my senior year at Barrett the Honors College majoring in both Biological Sciences (Neurobiology, Physiology and Behavior) (BS) and Psychology (BS), and looking forward to attending medical school to pursue a career in orthopedic surgery. I joined Dr. Bimonte-Nelson’s lab in the fall of 2018, and it has been an honor and a pleasure to be part of such an incredible team and diving into fascinating behavioral neuroscience research. I look forward to working on my own honors thesis research this year!.
